The grotto features two hidden doors: one on a southern portion of wall guarded by an Iron Knuckle, and the other on a western portion of wall underwater.
Behind the last hidden door lies a room in which a Dark Interloper resides along with an empty chest and some rupees. The ghastly being wields the Hookshot and may use it in battle against the player.
Background and Inspiration Edit
The Falkreath Secret Grotto was added to Relics of Hyrule in version 5.3 and was later expanded in version 6.27. The expansion was finalized in version 6.3. The grotto was modified in subsequent updates to be more easily traversed by followers.
Prior to its expansion, the grotto only included the areas with the Zora Soldier Helmet and the Iron Knuckle.
